Answer:
x-3
Step-by-step explanation:
(x^2-9)(x^2-9)/x^2*(x+3)+9(x+3)
(x+3)*(x^2+9)/(x+3)*(x^2+9) cross multiply 
(x^2+9)*(x+3)/(x^2+9) cross multiply
x+3 final anser

Answer:
ASA  and AAS
Step-by-step explanation:
We do not know if these are right triangles; therefore we cannot use HL to prove congruence.
We do not have 2 or 3 sides marked congruent; therefore we cannot use SSS or SAS to prove congruence.
We are given that EF is parallel to HJ.  This makes EJ a transversal.  This also means that ∠HJG and ∠GEF are alternate interior angles and are therefore congruent.  We also know that ∠EGF and ∠HGJ are vertical angles and are congruent.  This gives us two angles and a non-included side, which is the AAS congruence theorem.
Since EF and HJ are parallel and EJ is a transversal, ∠JHG and ∠EFG are alternate interior angles and are congruent.  Again we have that ∠EGF and ∠HGJ are vertical angles and are congruent; this gives us two angles and an included side, which is the ASA congruence theorem.
 
        
                    
             
        
        
        
$56.25
8:25 - 4:25 = 4 hours 
4 hours - 1 hour for lunch = 3 hours 
$18.75 x 3 = $56.25
